Digital modem (Menu 30 2)

As of SW 2.0.2, the motherboard (MB) will include a digital modem which can be used for re-
mote system administration. An external modem is thus no longer needed, provided digital
trunk lines (STLS modules) are available.
The digital modem is treated as a pseudo port and is assigned an extension number (879, can
be altered) in the system which can be reached internally using DDI. The DDI number can be
manually cancelled to prevent external access.
An individual 6-digit PIN code can be programmed by the customer in the system administra-
tion (access with password). This PIN code must be entered in the PC tool. The default setting
for the PIN code is not sufficient to access the digital modem.
This means that the customer must specifically release access to the digital modem by entering
this PIN code.
The PIN code can, if necessary, be reset to the default value via the password-protected system
administration (programming telephone only, not PC tool).
An MSN no. can also be assigned for an extension as can a DDI no. for remote ad-
ministration.
An extension number that has already been assigned to an extension can be as-
signed per DDI.
7.9.3

DTMF remote administration and maintenance

As of SW 2.0.2, the system can also be programmed using DTMF signalling. This enables the
system to be remotely administered and maintained without difficulty. The passive DTMF re-
mote AM feature must also be released in the slave system (customer system). In addition, the
party called must release remote AM for the current connection using the appropriate proce-
dure and specifying a password (6 characters).
Active DTMF remote administration and maintenance mode can be activated in the remote
master system (service system) by each user using the same code procedure (but a different
password). Active remote administration and maintenance must always be released in the mas-
ter system. The slave system (customer system) can be programmed from the master system
by means of DTMF signalling. The extension in the slave system is activated.
DTMF administration and maintenance is only available via analogue trunk lines up to
SW 2.0.2.
As of SW 2.1, the DTMF remote AM feature can also be activated via S
